Description

Abstract:

In this talk, the Belle II experiment will be discussed, focusing on the Central Drift Chamber (CDC). SuperKEKB, the asymmetric energy accelerator that provides e+e− collisions inside Belle II, achieved a new luminosity world record of 4.7x1034 cm−2s−1 (2022) and 5.1x1034cm−2s−1 (2024).

The Central Drift Chamber is currently showing good performance. However, with the expected increase in luminosity in future runs, it will be necessary to keep stable operation and good performance even in higher background conditions. We will then look at how beam backgrounds affect the operation and performance of the CDC, and describe possible countermeasures for the future.
